At first sign in frenzo with you id.

Now edit any bookmark/ web address. You will find like that: http://m.frenzo.com/messageboard/OwnersMessageBoard,MainMenuLink.DirectLink.sdirect;jsessionid=9A3DA58B2C96CD6CB5D609D195K335EF?ts=232

Now look at the link. You will find there jsessionid=9A3DA58B2C96CD6CB5D609D195K335EF Its your session id. And it will remain same at every page until you sign out.

Thus you can understand that session id plays an important role. If you can collect the current session id of your friend, You can open his id, just by replacing your session id with his/her session id. Also you do not require his/her user id and password.

Its a cool trick and fully depend on how u collect the session id from ur friend. Now, don't tell me to teach you how to collect it from your friend!!! ha ha ha....!!!
